Hello,

Thanks for the merge request

I setup an environment (clone ...) to be able to do it

Question : how can I generate the documentation when I modify WSDG_chapter_dissection.adoc ?

Thanks,

Olivier

Hi,

Thanks for having a look and reporting back. This could have been done as a merge request, this works as well. I’ve created one on your behalf, see WSDG: update protocol stats section to match current API

Further comments are inline.

Thanks,

Jaap

Hello all,


Questions/remarks about https://www.wireshark.org/docs/wsdg_html_chunked/ChDissectStats.html


1) An include is missing :
Solution :
Add #include <epan/stats_tree.h>

Done

2) msgtypevalues does not exist
Solution :
Replace "msgtypevalues" by "packettypenames"
 to be conform with previous § 9.2.3. Improving the dissection information (https://www.wireshark.org/docs/wsdg_html_chunked/ChDissectAdd.html)

Done

3) st_node_packets = stats_tree_create_node(st, st_str_packets, 0, TRUE); does not compile
Solution :
Replace it by :
    st_node_packets = stats_tree_create_node(st, st_str_packets, 0, STAT_DT_INT, TRUE);

Done

4) foo_stats_tree_packet has bad prototype
Solution :
foo_stats_tree_packet should return tap_packet_status / TAP_PACKET_REDRAW (instead of int / 1)

Done

About register_foo_stat_trees

5) WS_DLL_PUBLIC_DEF void plugin_register_tap_listener(void) does not compile :
1>T:\wireshark\dev\build_sources_3.4--win64\wireshark\plugins\epan\foo\packet-foo.c(192,1): error C2491: 'plugin_register_tap_listener' : définition de fonction dllimport non autorisée
1>Génération du projet "foo.vcxproj" terminée -- ÉCHEC.
"Solution" :
Use __declspec(dllexport) instead of WS_DLL_PUBLIC_DEF

Nope, this is what ws_symbol_export.h is in place for, to have a cross platform abstraction of dynamically linked identifiers. The build system has to take care of this, the Windows one is especially finicky about the details.

6) __declspec(dllexport) void plugin_register_tap_listener(void) is never called
Solution ? :
- remove it
- call directly register_foo_stat_trees(); from proto_reg_handoff_foo

It is the good way to do ?

Again, this is what the build system is taking care of, to create cross platform abstractions of the dynamic link linking.

Thanks,
Olivier
